We here perform a secondary analysis of kynurenine metabolites and MCP-1 in cerebrospinal fluid of 23 twins affected from schizophrenia, bipolar disorder or unaffected.
Levels of monocyte chemoattractant protein-1 (MCP-1/CCL2), macrophage inflammatory protein-1β (MIP-1β/CCL4), Eotaxin-1 (CCL11), thymus and activation-regulated chemokine (TARC/CCL17), and macrophage-derived chemokine (MDC/CCL22) were significantly higher in persons with schizophrenia than HCs.
Serum levels of interleukin-4 (IL-4), IL-6, IL-10, IL-17, interferon (IFN-γ), and (C-X-C motif) ligand 10/interferon gamma-induced protein 10 (CXCL10/IP10) were decreased, while levels of the chemokine (C-C motif) ligand 2/monocyte chemoattractant protein-1 (CCL2/MCP-1) were increased in the schizophrenia group in comparison with controls.
Aim We aimed to investigate a potential link between chemokines and schizophrenia and analyze the role of MCP-1-A2518G, SDF-1-3'A, CCR5-delta32, CCR5-A55029G, CXCR4-C138T and CCR2-V64I gene polymorphisms in the Turkish population.
In conclusion, we report here the association of the -2518A/G genetic polymorphism and increased plasma levels of MCP-1 with schizophrenia and nominate -2518*G minor allele as a risk factor for schizophrenia in Armenian population.
The aim of this case-control study was to investigate the potential role of SCYA2 (A-2518G polymorphism) in conferring susceptibility to schizophrenia and to the resistance to antipsychotic treatment.
The present study therefore calls for further studies on the potential role of the MCP-1 promoter -2518 polymorphism in clinical heterogeneity of schizophrenia.
